      Align temp buffer to 16 byte boundary · c1c502b8
      Yaowu Xu authored
      The optimized instrinsics require the buffer to be aligned on 16 byte
      boundaries. The commit fixes segfaults caused by unaligned access.

      Refactor ext-intra · 45dc597a
      hui su authored
      Miscellaneous changes. Mostly code simplification and cleanup.
      
      Make luma max angle delta depend on block size, which is the
      way it was before the nextgenv2 branch merge.
      
      Also some fixes for compatibility of ext-intra and alt-intra.

      Change scaling of rectangular fwd transforms · f0aa420c
      Debargha Mukherjee authored
      Modifies the C fwd txfms to have correct scaling. Rectangular
      transforms now are always implemented in a way that the samller
      side is transformed first.
      
      The SSE2 tests are temporarily disabled until the SSSE2 code
      is modified to be consistent with the C code.
      
      Also includes a fdct32 fix.
      
      borgtest results show a slight improvement.

      Disable filtering for Cb and Cr components · 818e42a7

      The parameters are optimized only on Y, so disable chrominance
      filtering for now. Later we can extend the syntax to have
      separate parameters for the chrominance, or optimize the
      parameters jointly over luminance and chrominance components.

      Not to call reset_use_upsampled_references() while encoding key frames · fe1e58ec
      Yunqing Wang authored
      A crash was reported while encoding >1080p file using best mode.
      (aom issue 107 and issue 108). The cause was that the speed features
      were initialized using good mode in AV1. The patch(commit f330ca)
      disabled the upsampled reference usage only for good mode, but not for
      best mode. So, for 1st key frame, the encoder incorrectly called
      reset_use_upsampled_references() that caused the segfault.
      
      The patch(commit e4e93b) disabled the upsampled reference usage for all
      encoding modes and resolved the issue. This patch fixed issue 108 and
      further made sure the upsampled references would be used correctly.
